RADIO energy in all its
original volume is delivered by antennae equipped with
Signals from even the most distant stations reach the
detector unweakened by leakage or eddy losses.
The special glass from which PYREX Radio
Insulators are made has the lowest power loss of any
known substance suitable for antenna insulation, with
the exception of fused quartz. The smooth hard surface
prevents accumulation of dirt and soot.
Specified wherever perfect insulation is of
vital importance -- in the U. S. Navy,
Coast Guard, Lighthouse and Air Mail -- and in the
country's largest broadcasting stations.
